JOHN A. WILSON, OF BALTIMORE, MARYLAND.

GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 233,451, dated October 19, 1880.

Application filed April 29, 1880. (No model.)

To all 'whom 'it may concern:

Be it known that I, JOHN A. WrLsoN, a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvcments in Gas-Governors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in governors for regulating the pressure of gas between the meter and burner.

The object of the invention is to adjust the pressure so that it shall not be excessive, and to secure a uniform pressure at each burner, whether one or a dozen burners be lighted,

thereby preventing the waste which results from blowing.

The construction of my improved apparatus will first be described and its operation explained, and those parts constituting the invention will then be designated in the claims.

In the drawings hereto annexed, Figure 1 is a vertical section, and Fig. 2 a cross section, of my apparatus.

The letterAdesignates the outer case, which incloses the operative parts of the device, and is, preferably, cylindrical in shape. The lower portion of this cylinder is internally divided into three compartments, (designated by the figures l, 2, and 3.) Oompartments 1 and 2 are annular in shape, and are formed by the metal division-walls b c, the latter of which also forms the central circular compartment, 3, at the bottom of which enters the gas from the inlet-pipe d after it has passed the meter.

The letter E designates the diaphragm, which is the circular top of a lloat, which has depending from its lower side two annular divisions, f g. This Heat has a' bail, h, attached at the upper side of the diaphragm, and a lever, I, is attached by one end to the bail, and is pivoted to across-rod, 7c, whose ends arc secured to the inner sides of the cylinder. The

other end of the lever is screw-threaded, as

seen at c', and a balance-weight, n, is tapped through its center and threaded, so as to be adjusted on the threaded end of the lever.

By means of the bail-lever l and cross-rod the diaphragm or oat is suspended in such manner that its divisions f g hang Within the lower compartments, l and 2, respectively, which are each filled to within a short distance of the top of their walls with some suitable Huid, such as a mixture of linseed-oil and glycerine, or any oil or other mixture which will not be readily affected by the gas and will not be quickly evaporated. This construction permits the iioat to rise or lower, and at the same time prevents the escape of any gas which may be in the central compartment. Thus the diaphragm or top E constitutes for the central compartment, 3, a tight cover, which may be raised or lowered as the internal pressure is greater or less.

Around the opening in the bottom through which the gas enters is a short stand-pipe or curb, p, which serves to retain any of the liquor which results from condensation, and prevents the same from flowing down the regulating-valve. At one side of the curb a drawoff pipe, q, is attached, having a faucet, q', by which the liquor may be removed whenever enough has accumulated.

The regulating-valve r is suspended by the vertical rod s, which is attached to the diaphragm. The rod plays endwise through an eye or guide, t, which is supported by braces u, attached to the walls c of the central compartment. When the diaphragm is raised by the gas-pressure within the central compartment the valve is brought up against its seat and the gas-supply cut off. Thus the floating diaphragm operates the regulatin g-valve.

The letter c designates the outlet-pi pe which supplies the gas to the burners, and y a removable cap in the top of the outer case to permit of adjusting the balance-weight.

From the foregoing description the operation of m'y apparatus will be readily understood bythe following additional explanation: The balance-weight must be adjusted to the pressure from the street-main in such manner as will yield a maximum light from one burner Without blowing, thc object being' to burn gas underlow pressure. When thediaphragm, with the valves suspended therefrom, is thus balanced to vield a satisfactory light from one burner, it will be found to work with the same result when three, four, or a dozen additional burners are lighted.

Having described my invention, Iclaim and desire to secure by Letters Patentof the United States- 1. In a gas-governor, a vertical cylinder having in its lower portion two annular compartments, and a tloating diaphragm having two annular divisions depending from its lower side and suspended within the compartments
